ATTINY12-8PC

Overview

The ATTINY12-8PC is an 8-bit microcontroller based on the AVR RISC architecture, manufactured by Microchip Technology (formerly Atmel). It features 1K byte of in-system programmable Flash program memory and 64 bytes of EEPROM data memory. The device operates at a maximum clock frequency of 8 MHz with a supply voltage range of 4.0V to 5.5V. It includes 32 general-purpose working registers, one 8-bit Timer/Counter, an analog comparator, and a programmable watchdog timer. The component is housed in an 8-pin PDIP package.

Feature Summary

• High-performance 8-bit RISC architecture executing most instructions in a single clock cycle
• In-system programmable via SPI port for Flash and EEPROM
• Low-power operation with Idle and Power-down modes
• Integrated internal calibrated RC oscillator

Applications

• Embedded control applications
• Battery-powered devices requiring low power consumption
• Simple sensor interfaces using analog comparator
• Basic timing functions using 8-bit timer/counter

Procurement Notes

Verify that the specific part number matches the required speed grade and voltage range. Confirm the package type corresponds to the design requirements. Check for any obsolescence notices as this series may be marked not recommended for new designs. Ensure compatibility with existing programming tools and development environments.

Selection Notes

Select this component when a simple 8-bit controller with minimal I/O is sufficient. Consider the 4.0V to 5.5V operating range for power supply constraints. Evaluate the need for EEPROM storage versus simpler alternatives without non-volatile data retention. Assess if the 8 MHz speed meets processing requirements.

Part Context

This device belongs to the ATtiny11/12 family of microcontrollers. It shares architectural similarities with the ATtiny11 but adds EEPROM and SPI programming capabilities. The family utilizes high-density nonvolatile memory technology combined with an RISC CPU for cost-effective embedded solutions.

Replacement Considerations

Public confirmed substitute part numbers: ATTINY12-8PU, ATTINY12-8PI, ATTINY12-8SU.
